A Japanese adult visual novel series developed by Girlish and later adapted into an anime. The story follows the comedic and erotic misadventures of a young man entangled with several girls, with the plot centered on romantic misunderstandings, sex comedy, and increasingly chaotic situations. It is known for its explicit content and for being part of the broader eroge-to-anime trend. The title is usually associated with its original visual novel rather than a long-running franchise.
